Document Summary
Sustainable cities idea: cities are key to environmental sustainability, idea draws on larger sustainable development concept: development that meets needs of present without compromising ability of future generations to meet own needs". Compact cities: early idea was compact, high density cities. Reduce energy consumption district heating and cooling. Revitalize inner-city areas: this policy was formally endorsed by the eu in 1990, and forms basis for the urban renaissance" policies of the uk, places to grow" and greenbelt in ontario, growth boundaries, intensification, brownfield redevelopment. Sustainabletransport: a big issue is car use, in low-density cities, gasoline use is much higher, as shown by newman. & kenworthy: higher density urban forms might allow less car use. Challenges to compact cities: the compact city idea was soon challenged, many have argued that simple high density does not solve anything by itself. Energy use for heating, cooling, and waste management may be higher per capita in very high-density settlements.
